LAMP.

Specification of Letters Patent No. 32,930, dated July 30, 1861.

To all whom it may concern:

Be it known that I, U. B. VIDAL, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and ImprovedLamp; and I do hereby declare-that the following is a full, clear, andexact description of the same, reference being had to the annexeddrawings, making a part of this specification, in which- Figure 1 is anexternal view of my invention. Fig. 2 is a vertical central section ofthe same.

Similar letters of reference indicate corresponding parts in the twofigures.

The object of this invention is to obtain a small hand or portable lampfor burning coal oil without a glass chimney. To this end I employ awick with an expanded upper end, and use in connection therewith asliding tube or flame spreader which is fitted on the wick-tube andarranged as hereinafter shown and described.

The handle of the lamp is also arranged to form a match receptacle andthe bottom of the lamp provided with a corrugated or roughened surfacefor the purpose of enabling the matches to be ignited thereon.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A represents the body of the lamp which may be constructed in any of theknown forms, and B is a wick-tube which passes through the cap C, of thelamp. This wicktube may be of flat form and on it a sliding tube D, isplaced and allowed to slide freely. The wick tube B, has a sunken racka, at one side, and the sliding tube D, is provided with a pawl E, whichengages with the rack a, and retains the tube D, at any desiredpoint-see Fig. 1.

The upper end of the sliding tube D, has an expanded top F, and theupper end of the wick G, is split or divided longitudinally,

and spread out in fan-form like the top F, of tube D, as shown clearly,in Fig. 2, at F The wick G, should be quite compact in order to preventthe too free ascent of the oil.

By having the top of the wick G, split or expanded and covered by theexpanded top F, a wide or broad flame is obtained so that a large areais exposed to the air, and perfect combustion, and consequently abrilliant flame produced. The height of the flame is regulated byraising and lowering the tube D.

H represents the handle of the lamp. This handle is formed of an uprighttube Z), the lower end of which is attached to the bottom of the lamp,and the upper part connected to the outer end of a horizontal arm 0, theinner end of which is attached to the lamp A. The upper end of the tube6, is provided with a hinged lid or cap cl, and said tube forms a matchreceptacle. The tube I), may be of rectangular form in its transversesectionthat would be the preferable shape. The bottom 6, of the lamp hasa corrugated or a roughened surface formed in any proper way, in orderto afford a convenient means for igniting the matches to light the lamp.

The whole forms a very simple, convenient and compact portable or handlamp, and one which may be economically constructed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The handle H, corrugated or roughened bottom 6, expanded wick top F, andsliding tube D, with flame spreader F, attached; all being arranged asshown to form a new article of manufacture for the purpose specified.
